Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a self-locking titanium cable fixation and locking buckle for fracture surgery. Background Technology

[0002] In fracture surgery and hip replacement adjuvant therapy, titanium cable fixation technology is widely used due to its minimal invasiveness and high adaptability. Its core lies in achieving stable fixation of the titanium cable through a locking buckle. Traditional fixation methods rely on clamps to mechanically compress the locking buckle, deforming it to press the titanium cable. However, this method has significant drawbacks: First, the fixation effect is uncontrollable: affected by the surgeon's operating force and the precision of the clamps, the deformation of the locking buckle varies greatly, easily leading to titanium cable slippage (especially after the patient bears weight), resulting in a second surgery. Second, the operation is risky: to avoid loosening, the surgeon may repeatedly clamp the cable, or excessive force may cause the locking buckle to burst, prolonging the operation time and increasing the risk of infection. Finally, the compatibility is poor: traditional locking buckles are not well-suited to titanium cables, and the lack of anti-slip design further exacerbates the risk of loosening. Therefore, we propose using a self-locking titanium cable fixation locking buckle for fracture surgery. Utility Model Content

[0003] The purpose of this invention is to provide a self-locking titanium cable fixation and locking buckle for fracture surgery.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a self-locking titanium cable fixation locking buckle for fracture surgery, comprising a locking buckle body and a threaded compression sleeve. The locking buckle body includes a threaded hole, a through hole, and a front chamfer. The threaded hole is opened at the top of the locking buckle body and extends into the interior of the locking buckle body. The through hole is opened on the side of the locking buckle body and penetrates through the locking buckle body. The threaded compression sleeve includes a self-holding perforation and a thread. The thread is fixedly connected to the self-holding perforation, and the threaded spiral is installed inside the threaded hole.

[0005] As a further embodiment of this utility model, the side surface of the top of the locking buckle body is provided with a front chamfer.

[0006] As a further embodiment of this utility model, the locking buckle body is made entirely of titanium alloy.

[0007] As a further embodiment of this utility model: the inner wall of the through hole is provided with anti-slip texture, and the anti-slip texture is evenly distributed in a ring.

[0008] As a further embodiment of this utility model: the surface of the self-holding plum blossom is provided with anti-slip grooves, and the anti-slip grooves are evenly distributed along the edges of the self-holding plum blossom.

[0009] Compared with the prior art, the beneficial effects of this utility model by adopting the above technical solution are as follows:

[0010] 1. This utility model achieves precise control of locking force through the spiral engagement of the threaded compression sleeve and the locking buckle body. The standardized operation of the torque handle avoids instability caused by differences in the surgeon's force, reduces the slippage rate of the titanium cable, and at the same time, the threaded self-locking structure can withstand the continuous tension when the patient is bearing weight, eliminates the risk of secondary surgery, makes the locking effect controllable, and reduces the risk of slippage.

[0011] 2. This utility model, through its self-holding plum blossom anti-slip design and threaded fit, eliminates the need for additional instruments during installation. It can be fixed by tightening in one step, thereby shortening the operation time and avoiding the problem of locking buckle bursting due to repeated clamping by clamping forceps.

[0012] Other advantages, objectives and features of this invention will be set forth in part in the description which follows, and in part will be apparent to those skilled in the art from the following examination or study, or may be taught from the practice of this invention.

[0018] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0019] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see the appendix Figure 1 - Appendix Figure 4This utility model provides a self-locking titanium cable fixation locking buckle for fracture surgery, including a locking buckle body 1 and a threaded compression sleeve 2. The locking buckle body 1 includes a threaded hole 12, a through hole 11 and a front chamfer 13. The threaded hole 12 is opened at the top of the locking buckle body 1 and extends into the interior of the locking buckle body 1. The through hole 11 is opened on the side of the locking buckle body 1 and penetrates through the locking buckle body 1. The threaded compression sleeve 2 includes a self-holding plum blossom 21 and a thread 22. The thread 22 is fixedly connected to the self-holding plum blossom 21, and the thread 22 is spirally installed inside the threaded hole 12.

[0021] The above solution achieves precise control of the locking force through the spiral engagement of the threaded compression sleeve 2 and the locking buckle body 1. The standardized operation of the torque handle avoids instability caused by differences in the surgeon's force, reduces the slippage rate of the titanium cable, and at the same time, the self-locking structure can withstand the continuous tension when the patient is bearing weight, eliminating the risk of secondary surgery, making the locking effect controllable and reducing the risk of slippage.

[0022] like Figure 1 As shown, the side surface of the top of the locking buckle body 1 is set with a front chamfer 13;

[0023] The above solution improves the aesthetics of the device by creating a chamfer 13 on the side surface of the top of the locking buckle body 1, while also reducing friction and irritation with the patient's surrounding tissues.

[0024] like Figure 1 As shown, the locking buckle body 1 is made entirely of titanium alloy;

[0025] The above solution is adopted: by making the entire locking buckle body 1 from titanium alloy, it has good biocompatibility.

[0026] like Figure 3 As shown, the inner wall of the through hole 11 is provided with anti-slip texture, and the anti-slip texture is evenly distributed in a ring.

[0027] The above solution is adopted: by setting annular anti-slip texture on the inner wall of the through hole 11, the friction between the titanium cable and the inner wall of the through hole 11 can be increased, preventing the titanium cable from slipping when under force, ensuring the stability after fracture fixation, and avoiding reduction deviation caused by loosening of the titanium cable.

[0028] like Figure 1 As shown, the surface of the self-holding plum blossom 21 is provided with anti-slip grooves, and the anti-slip grooves are evenly distributed along the edges of the self-holding plum blossom 21.

[0029] The above solution enhances the engagement between the surgical instrument and the self-holding plum blossom 21 through the anti-slip groove, preventing slippage during operation, facilitating precise control of the tightening force of the threaded clamping sleeve 2, ensuring uniform fixing pressure of the titanium cable, and reducing the risk of titanium cable damage caused by over-tightening.

[0030] Working principle:

[0031] During the surgery, the titanium cable is passed through the through hole 11 of the locking buckle body 1 and wrapped around the fracture site to complete the binding. The tightness of the titanium cable is adjusted to fit the bone surface. The annular anti-slip texture on the inner wall of the through hole 11 can initially enhance the friction between the titanium cable and the locking buckle to prevent slippage during the pre-fixation stage.

[0032] Hold the self-holding plum blossom 21 of the threaded clamping sleeve 2, align the thread 22 at its bottom with the threaded hole 12 at the top of the locking buckle body 1, and screw it in with a plum blossom screwdriver. The anti-slip groove on the surface of the self-holding plum blossom 21 enhances the engagement with the instrument and prevents slippage when tightening.

[0033] Continue to rotate the threaded clamping sleeve 2, pushing it down along the threaded hole 12 until the end of the thread 22 clamps the titanium cable in the through hole 11. The screwing depth can be controlled by the torque handle, and the locking force can be precisely adjusted to ensure that the titanium cable is evenly clamped without damage. At this time, the self-locking force generated by the thread 22 and the friction force of the anti-slip texture work together to achieve stable fixation of the titanium cable.

[0034] After locking, the chamfer 13 on the top of the locking buckle body 1 reduces friction and irritation with surrounding tissues. The titanium alloy material ensures biocompatibility and structural strength. The operator can directly observe the locking status without secondary inspection or adjustment.
